Web12 sep. 2024 · The total binding energy (Equation 10.3.2) is B E = [ 2 m p + 2 m n] − m ( 4 H e) c 2. These masses are m ( 4 H e) = 4.002602 u, m p = 1.007825 u, and m n = 1.008665 u. Thus we have B E = ( 0.030378 u) c 2. Noting that 1 u = 931.5 M e V / c 2, we find B E = ( 0.030378) ( 931.5 M e V / c 2) c 2 = 28.3 M e V.
